Abstract

L'invention concerne un procédé et un appareil de détermination d'intervalle de durée prévu, et un procédé et un appareil de vérification de déplacement. Une paire de stations est constituée d'une station de départ de déplacement et une station de fin de déplacement ; selon de multiples éléments d'informations de déplacement dans le passé correspondant à la paire de stations, des durées passées par un utilisateur à partir de la station de départ de déplacement pour arriver à la station de fin de déplacement (c'est-à-dire, une durée de déplacement) dans de multiples déplacements dans le passé sont calculées ; et un intervalle de durée prévu correspondant à la paire de stations est déterminé sur la base du résultat de calcul. Lorsqu'un déplacement cible correspondant à la paire de stations est vérifié, si la durée de déplacement correspondant au déplacement cible tombe dans l'intervalle de durée prévu, il est déterminé que le déplacement cible a réussit la vérification.
